6 Claims.

The present invention relates to improvements inboilers as used in steam, hot water and vapor heating systems, and has for its object the provision of anapparatus in which a series of short coils of an easily replaceable nature and a type low in V cost and maintenance, are so utilized as to effectively and eiiiciently operate throughout a lengthy life.

A further object of the invention is an arrangement rand apparatus in and by which coils of a cast nature, more particularly of the vertical sectional radiator-type, may be effectively and efficiently utilized.

With the foregoing in mind it is believed vthe further objects as well as the resulting advantages of the present invention, may be fully understood and appreciated from the following description and the Yaccompanying drawings, disclosing the best mode so far devised for carrying :the invention into practice.

In the accompanying drawings, which form a part of this specification,

Figure 1 is a side elevation of the improved boiler, partly broken away and in section.

Figure 2 is a rear elevation, partlyibroken away Y and in section.

Figure '3 is a horizontal `section taken therethrough along about the line of the top of the combustion chamber, on line 3--3 of Figure l.

Figure 4 is a similar View taken on a line 4-4 of Figure 2 through the intermediate heater units, and

Figure 5 is a vertical sectional View from front to rear taken on line 5 5 of Figure 2.

Referring now to these figures, there is shown a vertically disposed rectangular boiler I having therein a combustion chamber I I to which access is had through a front door I2. While it is possible to use any desired means of producing heat by combustion in chamber I I, such as oil and gas, the furnace is shown with a space below the combustion chamber for use as an ash pit I3 in case solid fuel is used, necessitating a grate (not shown) between the combustion chamber I I and the ash pit I3. A front door I4 provides for access to the ash pit I3.

Within the combustion chamber I I single, cast vertical ra-diator units I are arranged parallel with, and adjacent to, the side walls of the boiler, these units being of a height approximately that of the combustion space. At the back of the combustion chamber are two single, cast vertical radiator type units I6 parallel with and adjacent to the rear wall, which are of substantially greater height and project at their upper ends approximately level with the upper ends of the 4,intermediate heater units I1.

,Above the combustion chamber, the internal area of the furnace is substantially fully taken up by the intermediate heater units Il and the upf per preheater units I8 and both of these banks of heating units consist of vertical sectional cast coils of the radiator type arranged in closely contiguous front and rear rows as plainly seen in Figures 1 and 5.

The upper kportions of the side units I5 of the combustion chamber II are connected by short pipes I9 with the lower portions of the intermediate heater units Ir'I as plainly seen in Figure l, and the lower portions of these side units I5 as Well as the lower portions of lthe rear units I of the combustion chamber are connected, by branch pipes 2El,.to pipes 2l leading downwardly from the upper ends of the upper preheater units I8.

Return pipes 22 lead the return flow of the systemor the water of condensation to the. lower portions of the preheater units, and feed pipes ,2,3 for the system lead from the upper portions of the intermediate heater units I'I. To the feed pipes 23, which in a steam system lead to va suitable steam drum (not shown), the upper ends of the rear vertically elongated units I6 of. the combustion chamber are connected by pipes V2li, and pipes v25 connect the extreme upper portionsrof the pipes 2 I, supplying the preheated fluid to the combustion chamber units I5 and I6, to the outflow or system feed pipes 23 so that in heating hot water, steam, if any, may flow directly from these units I6 and pipes 2I into the system feed pipes 23.

As seen particularly in Figure l, clean-out doors 26 and 21 normally give access to the upper preheater units I8 and the intermediate heater units I1 so that they may be easily maintained in a cleanly condition of maximum efficiency, and it is obvious any suitable inlet may be provided for replenishing the water of the system and any suitable outlet for draining the same.

In operation fluid returning to the boiler through the return pipes 22, is given a preheatingY in its passage through the upper preheating units I8 and when so preheated, passes downwardlyV through the pipes 2I to the lower portions of thesingle heater units I5 an-d I6 of the combustion chamber. The water heated in units I5, passes through the pipes I9 into the lower portions of the intermediate heater units I'I and after heating therein iiows outwardly through the feed pipes 23 into the heating system, or steam drum.

Y through the Vupper outlet pipes 24 thereof directly into the system feed pipes V23 a-nd in this way an effective and eicient arrangement is completed with the utilization of cast units of the vertical sectionalrradiator type throughout, insuring long life, and tion of parts.

What is claimed is: i Y c y l1."A boiler consisting of a shell having a combustion chamber in its lower portion, a series of single, cast radiator units lining said` chamber,
